+Added "-c" option to getinfo to execute command on data segment.
-<
+=====================
-<
+Version 4.3
->
+================================
->
+Version 5.0 (Released 9/18/2015)
+Changed rmtxop so it writes out same type as lesser of inputs unless
-<
+direction otherwise using -f? option.
->
+directed otherwise using -f? option.
+Changed order of oconv arguments in rfluxmtx so user can specify input
+octree using -i option at the end instead of (or in addition to) a
+Changed anisotropic Gaussian and Ashikhmin models so that
+illegal orientation vectors are dealt with more gracefully.
-+
-+
+Created wrapBSDF tool and incorporated into genBSDF along
-+
+with new rfluxmtx computation.
-+
-+
+Initial check-in of Roland Schregle's photon map integration.
-+
+New 5.0a version designation as suggested by Andy McNeil.
-+
-+
+Added left-hand coordinate sytems to rfluxmtx to correct
-+
+problems with coordinate axis orientations pointed out by
-+
+David Geisler-Moroder.
-+
-+
+Added color output to genBSDF (+C option) and support for
-+
+color rendering of Klems and tensor tree data.
-+
-+
+Fixed another bug in rsensor that caused rays to be generated
-+
+on opposite side of hemisphere even where sensitivity was zero.
-+
-+
+Fixed bug discovered by Jacob Jonsson in Klems BSDF
-+
+interpolator that caused it to over-predict normal
-+
+transmittance and reflectance.
-+
-+
+Added ability to read input from commands in dctimestep
-+
+and rmtxop.
-+
-+
+Added photon map support to rad.  Fixed some double-counting
-+
+issues in photon-mapping spotted by David Geisler-Moroder.
-+
-+
+Added photon map support to trad.
-+
-+
+Fixed bug in antimatter source testing when antimatter
-+
+definition follows potential obstructor in input.
-+
-+
+Fixed issue with missing character type identifier at head
-+
+of genBSDF XML output.
-+
-+
+Prompted by Roland S., added option to have pcompos -a order
-+
+rows from top rather than bottom of image.
-+
-+
+Changed dctimestep to accept matrix as well as BTDF input
-+
+in the VTDs invocation mode.  This permits the output of
-+
+rmtxop to be used in a pinch when combining multiple BTDF
-+
+layers, although interreflection between layers is not
-+
+accounted for properly as it is in the WINDOW program.
-+
-+
+Added Jan Wienold et al.'s evalglare to distribution.
-+
-+
+Hopeful fix to deadlock issue under Mac OS X 10.10.x (Yosemite).
-+
-+
+Fixed early exit of rcontrib with internal error (sample behind sender)
-+
+discovered by Rob G.
-+
-+
+=================================
-+
+Version 5.1 (Released 8/17/2017)
-+
-+
+Fixed issue with vchars.mta and symbols.mta not being installed in
-+
+the appropriate metafile library location, with help from Rob G.
-+
-+
+Added ability to give quoted strings to output= directive in rfluxmtx.
-+
-+
+****** COMPATIBILITY CHANGE ********
-+
+Added ability to digest color (CIE-XYZ) input in pabopto2bsdf.
-+
+This change alters the .sir (interpolant) format, so these files
-+
+will need to be regenerated.  Use the new "#colorimetry: CIE-XYZ" tag
-+
+to enable on input.
-+
-+
+Rewrote bsdf2klems to support tristimulus color and call wrapBSDF.
-+
+Did the same for bsdf2ttree.  Function specifications still gray only.
-+
-+
+Reduced a problem where rvu or rholo would be slow to quit when
-+
+run with many processes on a large model or one with a large
-+
+ambient file (taking lots of memory).  We were waiting for
-+
+processes to quit one-by-one, which takes some time for each
-+
+process as it disentangles its shared memory.  We now
-+
+wait for all the processes together, so they can disentangle
-+
+in parallel.  It can still take up to a minute in some cases,
-+
+but not 10 minutes like it was taking before the fix.
-+
-+
+Enabled ambient cache value corral for all levels, not just final two.
-+
+This may reduce errors in certain pathological scenes.
-+
-+
+Added -in option to rcalc, rlam, and total to limit the number of
-+
+input records in hopes of circumventing Windows EOF issues on binary data.
-+
+Also added -on option to rcalc and total for logical symmetry.
-+
-+
+Increased modifier limit to 10,000 in rcontrib.
-+
-+
+Fixed issues with glrad and added zoom response to mouse wheel input.
-+
-+
+Added missing definition of "ashik2" material type to reference manual.
-+
-+
+Changed genBSDF to calculate device thickness assuming Zmax==0 so
-+
+pkgBSDF will generate correct proxy geometry.
-+
-+
+Created pabopto2xyz tool to combine different sensor measurements
-+
+into a single CIE-XYZ measurement file for color BSDF interpolation.
-+
-+
+Jan Wienold updated evalglare to version 1.30
-+
-+
+Roland Schregle added out-of-core photon mapping routines, which
-+
+may be compiled using the PMAP_OOC macro.
-+
-+
+Added -a option to getinfo for easy addition of header lines.
-+
-+
+Fixed issue with multiple records on picture output in rcontrib (and rfluxmtx).
-+
+Credit to Sarith Subramaniam for pointing out the problem.
-+
-+
+Made mkillum more tolerant of non-planar polygons in its sampling routines.
-+
-+
+Added "-recover" option to genBSDF to pick up where it left off.
-+
-+
+Fixed genBSDF issue that was created incorrect normalization of
-+
+Klems output.  Thanks to David G-M and Christian Knoflach for
-+
+discovering the error.  Also improved sampling of indirect irradiance
-+
+that showed some slight bias due to poor sample collision avoidance.
-+
-+
+Fixed long-standing issue with -aa 0 neglecting textures in calculating
-+
+surface shading.
-+
-+
+Fixed bug in ranimove introduced during photon map integration.
-+
-+
+Added check for steep sections of BSDF in pabopto2bsdf, creating narrower
-+
+peakes in those places and mitigating some normalization issues.
-+
-+
+Added view360stereo.cal by Mark Stock to handle 360-degree over/under
-+
+stereo views.
-+
-+
+Added MAX2SHADE macro to place limit on number of light sources
-+
+to precheck for obstructions.  (Currently set to 200.)  This
-+
+avoids excessive start-up times for scenes with many light sources.
-+
+Thanks to Axel Jacobs for pointing out the problem.
-+
-+
+Added -v option to obj2mesh to print out mesh statistics.
-+
-+
+Rewrote bsdf2rad from ground up and made it a standard part of build.
-+
-+
+Fixed bug in orientation of Reinhart/Tregenza sample generator in rfluxmtx.
-+
-+
+Added ability to perform shadow-testing through unproxied BSDFs with strong
-+
+through (direct-direct) component.
-+
-+
+Added {+|-}a options to genBSDF and bsdf2ttree for switching off reciprocity
-+
+averaging.
-+
-+
+Added bias to see through BTDFs with a strong "through" component
-+
+rather than scattering view rays.  This is in lieu of peak extraction,
-+
+which looked to be too difficult from an implementation standpoint.
-+
-+
+Added bsdfview tool analogous to objview but for BSDF files (XML and SIR),
-+
+which calls bsdf2rad then rad with a few useful default views.
-+
-+
+=========================
-+
+Version 5.2 (Release October 8, 2018)
-+
-+
+Created psketch program to apply non-photorealistic rendering to selected
-+
+objects, identified by modifier name(s).
-+
-+
+Added '*' and '/' operations to rmtxop for element-wise multiplication and
-+
+division of same-sized matrices.
-+
-+
+Changed falsecolor so "-s" option is adjusted to match legend if one.
-+
-+
+Falsecolor legend changes and improvements by David G-M and Stephen W.
-+
-+
+Fixed bug in peak extraction code that generated
-+
+"Bad call to SDqueryTreProjSA" error, reported by Lars Grobe.
-+
-+
+Increased maximum luminance to 10^7 in pcond to fix issue noticed
-+
+by Axel Jacobs where veiling glare not added for the sun under
-+
+some conditions.
-+
-+
+Increased maximum number of open files in rcontrib to the system upper
-+
+limit of 2048 rather than the default 512 under Windows.
-+
-+
+Added top-level resources directory with files from Rob Guglielmetti.
-+
-+
+Improved accuracy for peaky BSDFs and small light sources.
-+
-+
+Fixed issue with pmapdump noted by Axel Jacobs.
-+
-+
+Improved accuracy of bsdf2ttree when converting scattering interpolation
-+
+representatons with strong peaks.
-+
-+
+Tweaked peak-extraction code to work more reliably.
-+
-+
+Georg Mischler updated SCons build system.
-+
-+
+Rob Guglielmetti and Alex Swindler updated CMake build system.
-+
-+
+Modified pcomb so the first view seen in the inputs is written into header.
-+
-+
+Wrote rtpict script to run rtrace in parallel mode and simulate rpict with
-+
+-n option.
-+
-+
+Added ability to move forwards/backwards specified distance in rvu "origin"
-+
+command.  Feature requested by John Mardaljevic, who essentially owns this
-+
+command, now.
-+
-+
+Reduced bias in ambient super-sampling method.
-+
-+
+Fixed bugs associated with zero transmission in chromatic tensor trees.
-+
+Thanks to Lars Grobe for pointing out issues.
-+
-+
+Added RAYPATH searching for -f options to genrev, gensurf, genworm,
-+
+bsdf2klems, bsdf2ttree, and pcomb.  This makes behavior consistent
-+
+with rcalc, calc, and rendering tools.
-+
-+
+Worked with Randolph Fritz to fix some issues with ies2rad and newer
-+
+IESNA63 standards.
-+
-+
+Resurrected original bsdf2rad test program, renaming it bsdf2rado. Still an
-+
+optional build in src/cv/.
-+
-+
+Fixed bug in rcontrib with virtual sources, where pretest was adding
-+
+to modifier accumulation buffers.  Reported by Mostapha.
-+
-+
+Added an "aBSDF" material type that explicitly checks for peak extraction.
-+
+Its arguments are the same as the original "BSDF" type, but without the
-+
+thickness parameter, as proxy geometry is not supported by this new type.
-+
+The old "BSDF" type no longer does peak extraction under any circumstances,
-+
+since this behavior is superfluous for proxied geometry.
-+
-+
+Added -r option to bsdf2rad (and bsdfview) to fix BSDF min and max range
-+
+for comparing BSDFs.
-+
-+
+Fixed issue with pfilt -m option and uneven image size changes pointed
-+
+out by Rob Shakespeare.
-+
-+
+Updates to evalglare and gendaylit from Jan Wienold, including new
-+
+colored sky option.
-+
-+
+=========================
-+
+Version 5.3
-+
-+
+Created radcompare program to compare Radiance tool output to reference outputs
-+
+during unit-testing.
-+
-+
+Fixed issue reading very large files (> 2 GBytes) in rcollate.
-+
-+
+Made picking function in rvu ignore transparent and void surfaces.
-+
-+
+Added -orRxX options to rtrace to enable output of mirrored and unmirrored
-+
+contributions and distances to enable new types of reprojections.  This also
-+
+cleaned up and unified handling of effective ray lengths throughout code.
-+
-+
+Bug fixes from Jan Wienold for evalglare.
-+
-+
+Changed indexed (numbered) output from dctimestep to start from 0 rather
-+
+than 1, to make it more consistent with expected input naming.
-+
-+
+Increased default sampling in bsdf2klems (-n option) to 1024.
-+
-+
+Fixed an issue noticed by David G-M that was causing genBSDF to bias
-+
+isotropic tensor tree samples resulting in subsequent failure of
-+
+peak extraction with "aBSDF" type.
-+
-+
+Introduced max() and min() functions to .cal library.
-+
-+
+Added random incident patch sampling to bsdf2klems to improve accuracy
-+
+with scattering interpolation representation input (e.g., from
-+
+pabopto2bsdf).  The other input types already sampled incident patch area.
-+
-+
+Added gendaymtx -A option to compute average sky over all the input
-+
+time steps.
-+
-+
+Added ability to output color image from rtrace with any of -ovrx options.
-+
-+
+Changed rlam behavior so -iaN reads N lines from a stream rather than N
-+
+characters.  This seems more useful, since -ibN is somewhat redundant with
-+
+the old behavior.
-+
-+
+Created rsplit program as compliment to rlam and to handle more complex
-+
+rtrace output into separate files or streams.
-+
-+
+Improved getinfo so that it can also hop over resolution string with -c
-+
+and header elide mode.
-+
-+
+Made pvalue -u option mean "uncompressed" with -r.  Also, allow skipping
-+
+bytes on standard input.
-+
-+
+Created rcode_depth tool to convert to and from a 16-bit/pixel portable
-+
+depth image encoding that uses a mix of linear and reciprocal distance
-+
+with explicit representations of 0 and infinity.  Code for loading these
-+
+depth maps is in src/util/depthcodec.{h,c}.
-+
-+
+Created rcode_norm tool to conver to and from 32-bit/pixel portable
-+
+surface normal representation, matching the one in src/common/dircode.c.
-+
+Code for loading normal maps is in src/util/normcodec.{h,c}.
